I finally achieved primary , secondary and weapon mastery. Got some cool player cards along with that. The thing I'm disappointed in is the fact that I went above and beyond getting everything g weapon level maxed. Only to find out there is nothing for achieving this :(
That's a serious amount of kills. So it took you around 50k for them all, well you certainly have had your moneys worth out of the game so far, you must have more than 20 days playtime invested so far and I'm sure you had a lot of fun while doing it too.
